Mastering the Art of Layering: Staying Warm and Comfortable in the Outdoors

When heading into the hills, getting your layering system right can make the difference between an enjoyable adventure and a miserable trudge. Layering isn’t just about throwing on as many clothes as possible—it’s about strategy, choosing the right materials, and knowing when to adjust. Let’s break it down.

Why Layering Matters

Layering allows you to regulate your body temperature, trap heat effectively, and stay dry. In fact, adding just one extra layer can increase your insulation by 20–30%, depending on the material and fit. It’s a versatile way to adapt to changing conditions, whether you’re trekking uphill or resting at the summit.

Essential Tips for Perfect Layering

1. Hats: The Unsung Heroes of Warmth

Pack multiple hats for flexibility—a lightweight beanie for strenuous climbs and a thicker, insulated one for colder moments. Designs that cover your ears are especially effective for keeping warmth in and cold winds out.

We’re big fans of a good nightcap, like the Enlightened Equipment Torrid Hood.

We’ve tested the Torrid Hood several times, and found it to be a lightweight, versatile, and highly effective addition to any cold-weather setup. With high-quality synthetic insulation, it stays warm even in damp conditions, unlike traditional down.

The hood provides excellent warmth for the head and neck, pairs seamlessly with quilts or sleeping bags, and features an adjustable drawstring for a secure fit that minimises heat loss. Plus, its quick-drying insulation is ideal for the UK’s wet environments!

The Torrid Hood is an affordable, functional, and lightweight choice for staying warm in cold weather—a perfect addition to your nighttime setup.

2. Synthetic Insulation for Wet Weather Conditions

Down is nature’s best insulator, but it has a major flaw: it’s ineffective when damp. Sweat or rain can quickly reduce its insulating power. Synthetic materials may not be quite as warm as down, but they retain much more warmth when wet, making them a more reliable choice in unpredictable weather.

The Outdoor Research SuperStrand™ LT Hoodie is the ultimate in lightweight, packable synthetic insulation. With warmth comparable to 700-800 fill down, it excels in wet conditions, resists wind and light rain, and compresses to palm-size at just 301 grams. Its smooth, low-stitch design enhances warmth, and the insulated hood ensures comfort in all seasons. Perfect for layering, it’s a go-to for four-season adventures.

3. Multiple Mid-Layers for Adjustability

Instead of one thick mid-layer, opt for several thinner ones. This setup gives you more flexibility—shed a layer when you’re working hard uphill and add one when you stop or the temperature drops.

We really like the OR Polartec® 100 Quarter Zip as a midlayer because it combines lightweight comfort with excellent breathability and moisture-wicking properties. The quick-drying fleece makes it perfect for staying dry and comfortable during active outdoor adventures.

Another standout from Outdoor Research is the Astroman Air Sun Hoodie, which offers exceptional comfort and sun protection for demanding outdoor activities. Made from lightweight, stretchy, and durable recycled nylon, it’s designed to keep us cool and dry. The 3-panel hood and strategically placed laser-perforated holes provide maximum airflow, ensuring comfort during intense activities. With quick-drying fabric, a functional zip, and a chest pocket, it’s both a practical and versatile layer, making it perfect for everything from climbing to multi-day hikes in the sun.

4. The Science of Trapping Heat

Layering works by trapping warm air between layers, but this only happens if there’s space for air to circulate. Avoid tight clothing that compresses layers and reduces their insulating power.

5. Base Layer Basics

The foundation of your system, your base layer should wick moisture away from your skin. Choose materials like synthetic fabrics or merino wool, both of which excel at this task. Avoid cotton—it holds onto moisture and will leave you cold and clammy.

We really like the Outdoor Research Astroman Long Sleeve Sun Shirt as a base layer because it offers the perfect balance of comfort, performance, and sun protection for all-day outdoor activities. Made from the lightweight, stretchy, and durable Astroman fabric, it moves with you, providing unrestricted freedom during everything from climbing to hiking.

The AirVent technology on the back yoke is a standout feature, keeping you cool and fresh by promoting excellent airflow. The quick-drying fabric ensures you stay comfortable, even when things heat up, and the UPF 30-50+ protection keeps you shielded from the sun's harmful rays. It’s a reliable and versatile base layer for any adventure.

6. Extra Gloves for Happy Hands

Cold fingers can ruin any day out. Pack at least three pairs of gloves: lightweight baselayer liners, insulated gloves, and thin waterproof over-mitts for added protection.

We really like the Extremities Sticky Power Liner Gloves as a base layer or everyday glove because they’re lightweight, versatile, and perfect for cooler weather. Made with quick-drying Power Liner stretch fabric, they offer a cosy fleece lining for warmth, while the smooth outer provides a comfortable fit. The silicone grip print on the palm adds extra traction, making them ideal for activities that require grip. Plus, the touchscreen-compatible technology on the fingers and thumb makes it easy to use your devices without removing the gloves. They’re compact enough to stash in a pocket or backpack, so you’re always prepared when the temperature drops!

7. Protecting Pulse Points

Heat escapes quickly from areas with high blood flow near the surface, like your neck and wrists. Keep these areas covered with wrist warmers, a Buff, or a balaclava.

The Outdoor Research Vigor Plus Balaclava is excellent for its cold-weather performance and comfort. Made from bluesign®-approved materials, it’s designed with grid-backed recycled fleece that offers a perfect blend of warmth, stretch, and breathability. The movement-mirroring 4-way stretch provides a full range of motion, making it ideal for active cold-weather activities.

The hinge construction allows for adjustable coverage, making it adaptable to changing weather conditions. Plus, its water and wind resistance keep you protected from the elements, making it a go-to for maximum warmth and protection in cold environments.

8. Mastering Sock Layering for Winter Hiking

With over 250,000 sweat glands in your feet, proper sock layering is key to staying warm, dry, and blister-free. Start with snug, moisture-wicking liners made from merino wool blends (30–70% merino with synthetics) for warmth and sweat control, or opt for synthetics for durability or silk for softness.

Follow with midweight or heavyweight outer socks, depending on conditions, made from a merino wool blend (50–80% merino with synthetics) for insulation, breathability, and durability. Ensure both layers fit comfortably without compressing your feet to maintain circulation, and avoid cotton, as it traps moisture and loses insulation when wet.

We really like the Darn Tough Number 2 Micro Crew Midweight Socks because they offer the perfect balance of comfort, support, and durability. During our wild camping trips in Snowdonia, these socks provided just the right amount of cushioning without being too bulky, keeping our feet comfortable on long hikes and rough terrain.

Despite the wet conditions, they kept our feet blister-free, and after multiple trips, they showed no signs of wear. The snug fit stayed in place, and the socks maintained their shape and cushioning, offering long-lasting comfort. The lifetime warranty is a great bonus, reflecting the brand’s confidence in their quality.

9. Layering Your Legs

Don’t forget your lower half! If you tend to feel the cold, start with thermal leggings, add trousers, and top off with a waterproof layer. For others, winter-weight softshell trousers may provide enough insulation.

Outdoor Research Cirque Lite Pants are a top pick for 3-season rock and alpine adventures, combining durability, breathability, and flexibility. Made with bluesign® approved materials, the 88% nylon, 12% spandex fabric provides a comfortable, movement-mirroring fit, perfect for those who like to move fast and light in the mountains.

DuraPrint™ technology enhances durability for long days outdoors, while the gusseted crotch and articulated knees boost mobility. These pants are also wind and water-resistant, making them an excellent choice for nearly any 3-season mountain adventure. Plus, the integrated adjustable belt ensures a custom, comfortable fit every time.

10. Feet First: Socks and Boots Matter

A good pair of winter socks is crucial, but your boots are just as important. Make sure they’re waterproof before setting out to avoid cold, wet feet.

The Aequilibrium Hike GTX Gore-Tex Walking Boots are perfect for mixed terrain hiking, offering lightweight comfort without compromising on durability or protection. The synthetic fabric is breathable and abrasion-resistant, and the 3D Flex System Evo ensures natural ankle movement while providing stability and traction across all types of terrain.

With a 100% waterproof GORE-TEX Extended Comfort membrane, these boots perform in wet conditions while keeping your feet dry. The innovative Double Heel construction enhances walkability, and the Vibram tread outsole with Impact Brake System provides excellent control and precision. Resoleable treads increase the longevity of the boots, making them a solid choice for extended hikes in challenging environments.

Pro Tip: Adjust as You Go

Layering isn’t a “set it and forget it” system. Be ready to add or shed layers based on activity level and weather. Going uphill? Strip down a little to avoid sweating. Cooling off? Add a layer before you start feeling cold.

Mastering layering takes some practice, but once you get the hang of it, you’ll be ready to take on any conditions the hills throw your way. Stay warm, stay dry, and enjoy the journey!
